Redline Synthetic Manual Transmission Fluid : MT-90 75W90 GL-4 #17603

MT-90 75W90 GL-4 Gear Oil

• 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
• Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota
• Offers quicker shifts, perfect synchronizer coefficient of friction
• Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
• High performance gear protection and longer synchro life
• Eliminates notchy shifting, even when cold
• Satisifies the gear oil viscosity requirements of 75W, 80W and motor oil viscosities of SAE 40, 10W40, and 15W40
• Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified

ABOUT RED LINE GEAR OIL FOR MANUAL TRANSMISSIONS

• Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
• Red Line offers lubricants to pinpoint nearly every transmission application
• MTL, MT-85 & MT-90 are not for use in differentials with hypoid gears
• Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
• Excellent for high- and low-mile transmissions
• Compatible with petroleums and other synthetics
